Hi,

please can can you advise on the correct mcb for a 7.5kw 3 phase motor

Unfortunately to answer this we need to know quite alot about the motor.

Its method of starting. (Soft start device, DOL, star/delta etc)
Its starting curve to full speed and power.
Its duty (what does the motor actually do).

Once you get your answer then this can affect the required cable size in order to ensure permitted Zs values are complied with...

In a nutshell - from my previous recommendation in your other thread is to get in a competent Electrician or Engineer familiar with designing supply set-ups for machinery and motors, I take it that in asking this question you have not heeded that advice yet.
